Starting a D&D game at mid-level

[LibraryOgre]

So what sensory bonus does a gold dragon familiar give? I've got an elven fighter mage with a owl (night vision equals human daylight vision, superior hearing) and a longbow (I own the underdark!), and a human wild mage with a bat (auto detect invisibility via sonar out to 50 yards - also sees through most illusions).

The main benefit, of course, is "My buddy is a gold dragon." ;-)
